norem - Most of the flying was done with the typhoon frame. I have the FPV mount which pushes the camera forward a lot but I'm still going to get props in the way. I did see the post about it, if i didn't have a family and could easily disappear for a few days i would go.

Mike - Ill i did for the "inverted" flight was go high up, flip it into rate mode, slow the motors down considerably, and do a half flip. I then just played with the sticks a bit to keep here level and then finished the flip after i felt i dropped enough. You need to go real low on the motor though, almost to idle, or she will fight you and try to go out of control.
as for the contra motors i do have some feelings on them now. For X8, FPV, camera bird they are excellent. They get both props high and out of the camera view and if running a gimbal no worries about a prop strike on the gimbal. They are also very powerful and will give you more then enough thrust for whatever you throw at them. HOWEVER there internal parts need to be reworked. The bearings in are not very good at all, replaced one after a few hours of flight that literally fell apart, and in a crash if you go inverted you will be replacing at least one shaft. You can go to your LHS and pick up some small steel rod and cut that for a shaft but its still a pain to replace. You are also limited on prop selection as the bottom prop has to be reamed out to 8mm, no slow fly props here. Overall there a good motor for this application just be prepared for continuos work on them and good luck finding them as hobby king has been out of stock for almost 2 months now.

Very nice video, I'm impressed! I loved your choice of sites for scenic value. You do come rippin through the landscape at an impressive velocity. Real nice flying, and real nice production on the video.
